In an unprecedented move, Heathrow airport has told airlines to stop selling flights for this summer.
The aviation hub this morning announced a daily cap on passenger numbers until 11 September, saying that the airport could handle no more than 100,000 travellers each day.
The upshot is that carriers will have to suspend sales on seats as yet unsold - and that more flight cancellations are likely on the way.
